Proof step 34 from proof junkrefs-put-statfield (previous step)

junkrefs(str, r ' + acc, ty, st), is_obj(str, r, st) ∨ is_array(str, r, st), st[r -- _type] .type ≤ ty, ∀ str, ty, st, sk, val. junkrefs(str, acc, ty, st) → junkrefs(str, acc, ty, st[jvmref -- sk, val]) ⊦ r = jvmref, junkrefs(str, r ' + acc, ty, st[jvmref -- sk, val])

User applied rule case distinction

And obtained the following new goals

Proof step 20:
is_obj(str, r, st), junkrefs(str, r ' + acc, ty, st), st[r -- _type] .type ≤ ty, ∀ str, ty, st, sk, val. junkrefs(str, acc, ty, st) → junkrefs(str, acc, ty, st[jvmref -- sk, val]) ⊦ r = jvmref, junkrefs(str, r ' + acc, ty, st[jvmref -- sk, val])
Proof step 33:
is_array(str, r, st), junkrefs(str, r ' + acc, ty, st), st[r -- _type] .type ≤ ty, ∀ str, ty, st, sk, val. junkrefs(str, acc, ty, st) → junkrefs(str, acc, ty, st[jvmref -- sk, val]) ⊦ r = jvmref, junkrefs(str, r ' + acc, ty, st[jvmref -- sk, val])
